If a module has the same `public-module-name` as the module being
generated and its import is exported, merge it into the same generated
interface.
Fix various always-imported modules from being printed while here and
update all the tests that checked for them.

* [cxx-interop] Add Hashable conformance to imported enums
Previously, imported enums only conformed to RawRepresentable and Equatable,
so they could not be used as members of a Set or keys of a Dictionary.
This patch adds Hashable conformance to give them that ability,
as well as some test cases to clarify the expected behavior.
Existing test cases are updated to reflect this new conformance.

Generated interfaces for Clang modules used to try printing normal
comments between decls extracted from the header text. That was because
doc-comment was not common in C/ObjC headers. But mainly because of
"import as member feature" Clang decls aren't printed in the order as
they appear in the header file, the logic determinig which comment
belongs to which decl was not working property. We've decided to remove
that feature and only print the proper doc-comments as it has been
getting common.

Arguments in `SubscriptExpr` are visited since the recent `ArgumentList`
refactoring, but were being added to the containing `CallExpr`. Add a
node for the `SubscriptExpr` itself so that its argument is added there
instead of the `CallExpr`.
Also remove `key.nameoffset` and `key.namelength` from the response when
both are 0 to match the rest of the offsets and lengths.

If possible, add imported members to the StructDecl's LookupTable rather than adding them directly as members. This will fix the issues with ordering that #39436 poorly attempted to solve during IRGen.
This also allows us to break out most of the test changes from #39436.
Generated Swift interfaces for modules with overlays, like Foundation or Dispatch, currently contain `import Foundation`/`import Dispatch` statements.
These imports are redundant, and this change removes them.
This affects module interfaces, interface generation in sourcekitd, and
diagnostics. Also fixes a fixit that was assuming the 'OSX' spelling when
computing the source range to replace.

We used to compute the mangled name in other cases, but document structure is
a syntactic request and can't guarantee that the class/protocol we're getting
the mangled name of is valid in any way so it often breaks assumptions in the
mangler and causes it to crash. It's not clear if the runtime_name is actually
being used anymore, so this change restricts reporting it to just the cases
where we don't need to mangle.

It looks like we recently started binding extensions to their nominals in order
to continue to compute access levels via ValueDecl::getFormalAccess() after an
assertion was added to enforce that bindExtensions had been called before
anything tried to call ExtensionDecl::getBoundNominal() - which
getFormalAccess() depends on. Sourcekitd's syntactic requests are made on every
keypress in the editor though, so we shouldn't do any name binding (which may
require module loading) to keep them as fast as possible.
This patch restores the old inferAccessLevel() functions we used prior to the
switch to ValueDecl::getFormalAccess() (plus a few fixes) that does as much as
it can syntactically, without any name binding, and simply doesn't report the
access level in cases where it couldn't be computed without name-binding.
This also fixes an assertion hit we were getting trying to bind extensions in
inactive ifconfig clauses, which ASTScope doesn't support.

When looking for the SyntaxNode corresponding to a type attribute (like
@escaping), ModelASTWalker would look for one whose range *started* at the type
attribute's source location. It never found one, though, because the
SyntaxNode's range included the @, while the type attribute's source location
pointed to the name *after* the @.
Previously 'isSystemModule()' returns true only if the module is:
- Standard library
- Clang module and that is `IsSystem`
- Swift overlay for clang `IsSystem` module
Now:
- Clang module and that is `IsSystem`; or
- Swift overlay for clang `IsSystem` module
- Swift module found in either of these directories:
- Runtime library directoris (including stdlib)
- Frameworks in `-Fsystem` directories
- Frameworks in `$SDKROOT/System/Library/Frameworks/` (Darwin)
- Frameworks in `$SDKROOT/Library/Frameworks/` (Darwin)

This patch allows Parser to generate a refined token stream to satisfy tooling's need. For syntax coloring, token stream from lexer is insufficient because (1) we have contextual keywords like get and set; (2) we may allow keywords to be used as argument labels and names; and (3) we need to split tokens like "==<". In this patch, these refinements are directly fulfilled through parsing without additional heuristics. The refined token vector is optionally saved in SourceFile instance.
I noticed in a follow-up patch that if you just swiftc without passing Onone
these flags are not set and sometimes happen to default to right thing ... or
not; as can be seen by the test cases modified. For example, at Onone we are
supposed to include an extra swift module "SwiftOnoneSupport".
...which didn't do the right thing in the presence of ModuleMacro,
depending on the order the macros were referenced. Already covered by
test/ClangImporter/macros.swift, but it actually seems to improve the
behavior of some of the SourceKit tests as well.
Continuing rdar://problem/32199805, which is just "get macros working
with clang::ModuleMacro".
Store leading a trailing "trivia" around a token, such as whitespace,
comments, doc comments, and escaping backticks. These are syntactically
important for preserving formatting when printing ASTs but don't
semantically affect the program.
Tokens take all trailing trivia up to, but not including, the next
newline. This is important to maintain checks that statements without
semicolon separators start on a new line, among other things.
Trivia are now data attached to the ends of tokens, not tokens
themselves.
Create a new Syntax sublibrary for upcoming immutable, persistent,
thread-safe ASTs, which will contain only the syntactic information
about source structure, as well as for generating new source code, and
structural editing. Proactively move swift::Token into there.
Since this patch is getting a bit large, a token fuzzer which checks
for round-trip equivlence with the workflow:
fuzzer => token stream => file1
=> Lexer => token stream => file 2 => diff(file1, file2)
Will arrive in a subsequent commit.
This patch does not change the grammar.
Switch printing off of using Function's ExtInfo for autoclosure and
escaping, and onto the ParameterTypeFlags, which let us do precise and
accurate context-sensitive printing of these parameter type
attributes. This fixes a huge list of issues where we were printing
@escaping for things like optional ObjC completion handlers, among
many others. We now correctly print @escaping in more places, and
don't print it when it's not correct.
Also updates the dumper to be consistent and give a good view of the
AST as represented in memory. Tests updated, more involved testing
coming soon.
This patch fixes an importer problem which occurred for macros defined
in terms of two other macros which might not have been imported before.
For example, the macro CPU_TYPE_X86_64 (defined as CPU_TYPE_X86 |
CPU_ARCH_ABI64) in Foundation wasn't imported although the importing
logic was implemented.
importMacro is now called for each of the constituents before checking
the constant value.
...to value types. Do continue bridging BOOL to Bool and such.
If the Objective-C API author went out of their way to indicate
ownership, they're probably using the reference semantics for
something. Give them the benefit of the doubt and leave the properties
declared using reference types. (It's not that they wouldn't work
correctly using Any, but that it's obscuring the intended interface.
And any /specific/ bridged value types /might/ actually cause issues
by causing copies.)
There is one wrinkle here involving declarations in the "accessibility
protocols" on Apple platforms, which sometimes use methods and
sometimes properties. The Swift compiler already deals with these by
always importing these as methods, so treat these like any other
methods and use value types when relevant.

One minor revision: this lifts the proposed restriction against
overriding a non-open method with an open one. On reflection,
that was inconsistent with the existing rule permitting non-public
methods to be overridden with public ones. The restriction on
subclassing a non-open class with an open class remains, and is
in fact consistent with the existing access rule.
This flips the switch to have @noescape be the default semantics for
function types in argument positions, for everything except property
setters. Property setters are naturally escaping, so they keep their
escaping-by-default behavior.
Adds contentual printing, and updates the test cases.
There is some further (non-source-breaking) work to be done for
SE-0103:
- We need the withoutActuallyEscaping function
- Improve diagnostics and QoI to at least @noescape's standards
- Deprecate / drop @noescape, right now we allow it
- Update internal code completion printing to be contextual
- Add more tests to explore tricky corner cases
- Small regressions in fixits in attr/attr_availability.swift
Implements SE-0055: https://github.com/apple/swift-evolution/blob/master/proposals/0055-optional-unsafe-pointers.md
- Add NULL as an extra inhabitant of Builtin.RawPointer (currently
hardcoded to 0 rather than being target-dependent).
- Import non-object pointers as Optional/IUO when nullable/null_unspecified
(like everything else).
- Change the type checker's *-to-pointer conversions to handle a layer of
optional.
- Use 'AutoreleasingUnsafeMutablePointer<NSError?>?' as the type of error
parameters exported to Objective-C.
- Drop NilLiteralConvertible conformance for all pointer types.
- Update the standard library and then all the tests.
I've decided to leave this commit only updating existing tests; any new
tests will come in the following commits. (That may mean some additional
implementation work to follow.)
The other major piece that's missing here is migration. I'm hoping we get
a lot of that with Swift 1.1's work for optional object references, but
I still need to investigate.
The test was supposed to use a CF type, but it wasn't updated
for the switch from a naming convention to an attribute. This
restores the original intent (and unfortunately slides all the
offsets).
